XML Viewer Online

Need an XML viewer that opens a file without installing anything? Use this free online XML viewer to open XML, sitemap, RSS, Atom and SVG files directly in your browser. Drop a file or paste the code, and it appears as a collapsible tree, formatted source or a table you can export.

The file is parsed on your device with your browser’s built-in XML parser, so it is not uploaded to a server. You can search the data, run XPath queries, check sitemaps for common problems and download the result as XML, JSON or CSV.

How to View an XML File

To view an XML file, drop it onto the viewer above or paste its contents and press View. The tool parses the file in your browser and shows it as a tree you can expand and collapse, as formatted source with line numbers, or as a table of repeating items.

1. Open or paste your XML. Drop a .xml or .xml.gz file onto the drop zone, or switch to the Paste XML tab.
2. Read the detection panel. It shows what kind of file you opened (a sitemap, an RSS feed, an SVG or generic XML), the encoding, the size and any problems found.
3. Explore the data. Use Tree to collapse nodes and search for a tag, attribute or text. Use Source to read the formatted or minified code. Use Table to see repeating elements as rows.
4. Query or export. Run an XPath query, copy the XPath of any node, then copy or download the XML, JSON or CSV.

How Can I Open an XML File Online?

Open this page, drop your XML file onto the viewer and press View. The file is read locally by your browser, so you can open private feeds, configuration files, exports and sitemaps without uploading them anywhere.

The viewer accepts these file types:

• .xml and plain text files that contain XML
• .xml.gz compressed files, such as gzipped sitemaps, which are decompressed in your browser
• .rss and .atom feeds
• .svg images, which are XML underneath
• .kml, .gpx and .opml files

Can I Open XML in Chrome?

Yes. Chrome can open a local XML file and shows it as a basic collapsible tree. It does not give you a table view, XPath queries, encoding control, sitemap checks or an export to JSON or CSV. Use an online XML viewer when you need to analyse the file rather than just look at it.

How Do I Convert an XML File to Readable?

Switch to the Source view and choose Formatted to see the XML with clean indentation and line numbers. If your file contains repeating items, such as products, URLs or feed entries, open the Table view to read them as rows and columns. You can also download the data as JSON or CSV.

XML Viewer for Windows, Mac, Android and iPhone

This XML viewer runs in the browser, so there is nothing to download or install. It works the same on Windows, macOS, Linux, Android and iPhone. If you were searching for an XML viewer download, an extension or an app, you can use this page instead and keep your files on your device.

What Is an XML File?

XML stands for Extensible Markup Language. An XML file stores data as nested tags, which makes it easy for programs to read but hard for people to scan, especially when the whole file is on a single line. You will meet XML in sitemaps, RSS and Atom feeds, SVG images, Android and Java configuration files, SOAP messages, GPS tracks and data exports from older systems.

How to View a Sitemap.xml File

Open your sitemap.xml or sitemap.xml.gz in the viewer and it detects the sitemap automatically. The Table view lists every URL with its lastmod, changefreq and priority, and the Data Insights panel checks for:

• Duplicate URLs listed more than once
• Mixed http:// and https:// URLs
• Empty or relative <loc> values
• URLs with no lastmod, and the range of lastmod dates
• More than 50,000 URLs or a file over 50 MB, which are the limits for a single sitemap file

To validate the sitemap against the protocol, use the Sitemap Validator. To find pages that compete with each other, use the Sitemap Duplicate Content Scanner.

Why Does My XPath Return No Results on a Sitemap?

Sitemaps declare a default namespace, and XPath 1.0 cannot match elements in a default namespace without a prefix. A query such as //url therefore returns nothing, even though the URLs are there. In this viewer you can use the built-in ns: prefix, for example //ns:url/ns:loc, or the namespace-agnostic form //*[local-name()='url']. When a query returns no results on a namespaced document, the viewer tells you this.

What This XML Viewer Checks for You

File type. Sitemaps, sitemap indexes, RSS feeds, Atom feeds and SVG files are recognised and summarised, so you see the number of URLs, items or entries immediately.

Encoding. The viewer reads the byte order mark and the encoding declaration to choose the right character set, and you can override it if accented characters look wrong. It shows which encoding it used.

Security patterns. Files that contain a DOCTYPE, entity declarations or references to external resources are flagged. Your browser does not fetch external entities, but a server-side parser might, which is the basis of XXE attacks. Seeing the warning before you pass a file on is useful.

Errors. If the XML is not well-formed, the viewer shows the parser message and the lines around the problem, so you can find the mismatched or unclosed tag.

XML Viewer vs Other Ways to Open XML

Where This Tool Loses

This is a viewer, not an editor. You cannot change values, delete nodes or save edits, so use a desktop XML editor for that.

It checks that XML is well-formed, but it does not validate against an XSD or DTD schema, and it does not apply XSLT stylesheets. XPath support is XPath 1.0, which is what browsers provide natively.

Formatting trims whitespace around text, which is harmless for data files but can change the look of mixed content such as documents with text between tags. The Original view always shows exactly what you opened.

Everything runs on your device, so very large files depend on your browser and available memory. [FILL: add the largest file size you tested, for example “Tested with files up to X MB in Chrome.”] If a file is not UTF-8, choose the right encoding from the menu.
